BLF for Parked Calls on Linksys SPA932

Has anybody gotten this to work correctly on either Version 1.2 or 1.4?

I have Asterisk 1.4 and have configured the SPA 932 with 3 parking lots. The LEDs stay green all the time and do not show when a call is parked.

This is how I have the Asterisk configured under extentions_custom.conf

[from-internal-custom]

include => ext-parking-lot-custom

[ext-parking-lot-custom]
exten => 7001,1,ParkedCall(7001)
exten => 7001,hint,Local/7001@parkedcalls

exten => 7002,1,ParkedCall(7002)
exten => 7002,hint,Local/7002@parkedcalls

exten => 7003,1,ParkedCall(7003)
exten => 7003,hint,Local/7003@parkedcalls

On the SPA932, I have the following on three different keys:

fnc=blf+sd;sub=7001@ip_address;nme=ParkingLot
fnc=blf+sd;sub=7002@ip_address;nme=ParkingLot
fnc=blf+sd;sub=7002@ip_address;nme=ParkingLot

Is there something I am missing.

Thanks.
